IELTS Filler Words in Speaking: Which Ones to Use and Avoid

Most IELTS students panic when they pause.

They think silence equals failure. So they fill it. "Um," "uh," "like," "you know," "basically," "actually," "I mean." Sometimes all of them at once. Then they check their score: 6.5. They were aiming for 7.5.

Here's what they don't realize: IELTS examiners aren't listening for entertainment. They're listening for your ability to speak English naturally. But there's a twist. Some fillers destroy you. Others aren't fillers at all. They're cohesion devices. Strategic pauses. Thinking markers that examiners actually expect to hear.

Let me show you the difference, and why it matters for your band score.

What Examiners Are Actually Scoring

The IELTS Speaking test grades you on Fluency and Coherence. That's where your filler habits show up most clearly.

Band 7 says: "Speaks at length without noticeable effort or loss of coherence."

Band 6 says: "Hesitation which may affect communication."

One filler word won't drop you from 7 to 6. But this will: using too many filler words, using the wrong ones, or using them so frequently they become impossible to ignore. When an examiner hears "like" or "um" more than once per minute, they're actively downgrading your fluency.

The data backs this up. ESL speech studies show that high-level speakers use fillers at roughly 5-10 per 100 words. Lower-level speakers? 15-25 per 100 words. In a 10-minute IELTS Speaking test, you'll speak around 1,000-1,500 words. If you're in the lower-band range, that's 150-375 hesitations in one sitting. Examiners definitely notice.

Weak: "Um, like, I think, you know, technology is, uh, basically changing, like, how we communicate. Um, it's, uh, making things easier but also, like, more stressful."

Good: "I think technology is changing how we communicate. It's making things easier, though it also creates stress. For example, social media helps us stay connected, but it can feel overwhelming."

The second version has no filler words. It flows because the speaker uses complete thoughts and pauses instead of sounds.

IELTS Speaking Hesitation: Filler Words to Cut Entirely

Some filler words are pure dead weight. They add nothing and mark you as a lower-level speaker. Get rid of these:

Your goal isn't to reduce these. It's to eliminate them completely. Not reduce. Eliminate. If you can't do it in practice, you won't do it under test pressure.

Natural Speech in IELTS: Discourse Markers That Help You

Here's the good news. Some things that look like fillers aren't fillers at all. They're legitimate discourse markers. Examiners expect them. They're part of natural, fluent speech.

These are safe to use:

Good: "That's a good question. Let me think about that for a moment. In my opinion, the best way to learn a language is through regular exposure and practice."

This uses three strategic pauses, yet sounds completely natural and band 7 fluent. The speaker thinks out loud in English.

Why Silence Is Your Strength in IELTS Speaking

Silence is not your enemy.

A one-second pause? Perfect. Two seconds? Also fine. What hurts is filling that silence with "um" or "like." Examiners know thinking takes time. They expect it. Part 3 asks you about abstract topics with no prep time. No examiner expects instant answers.

The formula: pause, don't fill. You get asked a question, take a breath, organize your thought, then speak. This silence reads as confidence. Filling it with sounds reads as panic.

Practice drill: When someone asks you a question, count to two silently before speaking. Do this 50 times before your test. It becomes automatic. Under pressure, you'll pause naturally instead of filling the gap.

Real Examples: How IELTS Filler Words Kill Your Score

Let's look at an actual IELTS Part 2 topic: "Describe a memorable trip you took."

Weak response: "Um, so like, I went to Italy last summer with my friends. It was like, really amazing, you know? We visited Rome and, uh, it was basically incredible. Like, the Colosseum was so big and, um, we took lots of photos. You know, it's like, the experience changed me."

Count the fillers: um, like (4 times), you know (twice), basically, uh. That's 9 fillers in 65 words. The examiner hears hesitation and informal speech. Band 6.

Strong response: "I went to Italy last summer with my friends, and it was truly unforgettable. We visited Rome, where we explored the Colosseum, the Vatican, and the Roman Forum. What struck me most was the history embedded in every corner. Standing in the Colosseum, I felt connected to centuries of human civilization. The entire experience deepened my appreciation for architecture and culture."

Zero fillers. Complete, detailed thoughts. Band 7 fluency.

How to Actually Break the Filler Habit

Breaking a speaking habit requires deliberate practice. Here's the process:

  1. Record yourself on Part 1 questions. Pick 5 simple Part 1 questions: "Do you like your job?" "What's your favorite food?" "How do you usually spend weekends?" Answer each for 30 seconds. Play it back. Write down every filler word you hear. Count them.
  2. Do it again, but eliminate those fillers. Answer the same 5 questions again, but this time cut every filler you just identified. You'll speak more slowly. That's fine. Clarity beats speed.
  3. Move to Part 2 and Part 3. Part 2 gives you prep time, so fillers hurt less. But Part 3 throws complex questions at you with zero prep. This is where fillers spike. Practice Part 3 questions with a partner or use a speaking tool that gives real-time feedback.
  4. Time yourself under test conditions. Part 1 runs 4-5 minutes. Part 2 is 1-2 minutes of your talk. Part 3 is 4-5 minutes of discussion. Practice within these limits. Test pressure is what triggers fillers, so train under pressure.

Most students do this once and think they're fixed. They're not. The habit returns under stress. Practice it 10 times. 20 times. Until the correct behavior is automatic.

Part 3 Is Where IELTS Speaking Hesitation Costs You Points

Part 3 is where most students lose band points to fillers. You're discussing abstract topics without prep: "Why do you think young people are more interested in technology than older generations?" or "How has social media changed how we form relationships?"

These questions don't have right answers. They demand extended responses. And they trigger hesitation. That's where students panic and filler their way down.

Here's what a band 7+ response sounds like:

Band 7+ response: "I think there are several reasons. First, young people grew up with technology as the default, so it's more intuitive for them. Second, digital platforms offer instant gratification and connection, which is appealing. But I'd argue older generations aren't uninterested so much as more cautious about adoption. They've seen how technology can harm us, so they're more selective. From my perspective, it's less about interest and more about comfort level."

Zero um, uh, like, you know, basically. Instead: "I think," "First," "Second," "But," "I'd argue," "From my perspective." These are cohesion devices that sound organized and fluid. If you're working on structuring longer answers, how to give extended answers in Part 3 breaks down this exact technique.

When Silence Becomes a Problem

Silence isn't always your friend. If you pause for more than 4-5 seconds, the examiner wonders if you've lost your train of thought. That hurts fluency.

The sweet spot is 1-2 seconds. Long enough to think. Short enough to stay engaged. If you need more than 2 seconds, use a discourse marker: "Let me think about that," or "That's interesting," or "Well." This fills the gap with actual language, not sounds.

The goal: sound like you're thinking in English, not translating from your first language. A quick pause signals thinking. A long silence signals struggle.

Timing drill: Use your phone to time yourself during practice. Pause for 2 seconds. Feel how long it is. Then pause for 4 seconds. You'll hear the difference. Most students think 4 seconds is fine. It isn't. Stay at 1-2 seconds.

Questions Students Actually Ask

One or two instances of "um" probably won't tank your score. The safest approach is eliminating them entirely, especially if you're targeting band 7 or higher. There's no downside to avoiding them, and examiners expect near-zero filler sounds at higher bands.

Always pause. A 1-2 second pause is completely natural and expected during IELTS Speaking. The examiner won't penalize you for thinking time, but they will penalize you for filling that time with sounds or informal words.

Yes, but sparingly. One "so" or "well" per response is acceptable as a legitimate discourse marker. It shows organization and gives you thinking time. But if you start every sentence with "so," examiners will notice and mark you down for overuse.

Native speakers do use fillers casually, but IELTS Speaking is a formal assessment. You're graded on clarity, coherence, and fluency, not casual conversation patterns. Even native speakers reduce fillers during formal exams and presentations.

Record yourself answering practice questions, then play it back and count every filler. Answer the same question again while consciously avoiding those fillers. Repeat 5-10 times until it becomes automatic. You can also use AI speaking practice tools that flag fillers in real time.

The Practice That Actually Works

Recording yourself is the most effective drill you can do. You can't hear your own fillers in real time, but you can hear them on playback.

Here's the routine: answer a Part 1 question, play it back, count fillers. Then answer the same question again, avoiding every filler you heard. The difference is stark. Your second attempt sounds more confident, more fluent, and more controlled.

Do this with IELTS Speaking Part 1 topics first. Part 1 questions are simple ("Tell me about your family," "What do you do in your free time?"), so you can focus entirely on eliminating fillers instead of generating ideas. Once you're solid on Part 1, move to Part 2 cue cards and then Part 3 abstract questions.

The timeline matters. If you've got 4 weeks until your test, spend week 1 on Part 1. Week 2 on Part 2. Weeks 3-4 on Part 3. Part 3 is where fillers hurt most, so give it the most practice time.

What to Do Right Before Your Test

The night before your IELTS test, don't do anything new. Don't practice new vocabulary. Don't memorize new phrases. Instead, do a short "rehearsal" that focuses on your filler habits.

Spend 15 minutes answering Part 1 questions from your practice. Don't record. Just speak. Pay attention to when you feel the urge to use "um" or "like." Notice it. Then pause instead. This primes your brain to choose silence over fillers under test pressure.

On test day, your nervous system will want to fill silence. It's a natural stress response. But you've trained 50 times to pause instead. Trust that training.

During the test: If you catch yourself using a filler, don't panic. One filler won't drop your score. But make a mental note and adjust. Part 1 is your warm-up. If you're using fillers heavily there, consciously reduce them in Part 2 and especially Part 3. That's where your real band score is decided.

Finally, remember that fluency isn't about speaking fast. It's about speaking smoothly without hesitation markers. If you can eliminate fillers, you've solved half the fluency problem. The other half is choosing the right discourse markers and pausing strategically. Master both, and band 7 is within reach.
